No effect of short‐term exposure to ocean acidification on individual‐level variation in behaviour and susceptibility to predation in a Great Barrier Reef damselfish

Journal of Animal Ecology, EarlyView.
This study shows that projected ocean acidification does not alter behaviour or predation risk in coral reef fish, challenging earlier assumptions. By quantifying consistent individual‐level behavioural differences and relating individual traits to survival during a live‐predation trial, it also provides evidence for a boldness–predation trade‐off in a

Corallivore assemblage, feeding behavior, and cover of Acropora corals drive fish corallivory on tropical reefs

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Understanding spatial patterns and drivers of corallivory is essential for assessing reef resilience and identifying recovery pathways. Fish corallivory patterns arise from the complex direct and indirect effects of key factors, including food availability (cover of preferred corals), the nature of the corallivore assemblage (richness and ...

Molecular Mechanism of Absorption, Transport and Metabolic Transformation of Astaxanthin in Aquatic Animals

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
This manuscript systematically elucidates the molecular mechanisms underlying absorption, transport, and metabolism of Astaxanthin in aquatic animals, through the analysis of biological functions, transport proteins, and enzyme metabolism system. Furthermore, it outlines future molecular research strategies for Astaxanthin, providing a theoretical ...

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, Volume 109, Issue 2, Page 864-884, August 2026.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Effect of background color on the growth performance, digestive enzyme activity, antioxidant capacity, and intestinal microbiota of juvenile Plectropomus leopardus

Aquaculture Reports
The scale of Plectropomus leopardus breeding is continually expanding, and this has necessitated constant changes to ensure that breeding conditions are optimized. Background color is an important factor affecting fish feeding. In this study, fish (10.58

Interplay of Diet, Heat Stress, and the Microbiome Shapes Health and Escape Behaviour in Amphibian Larvae

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Diet and temperature jointly shape the gut microbiome and host performance in amphibian larvae. In a multifactorial experiment with Rana temporaria, diet quality, rearing temperature, and heatwave exposure altered microbial communities and predicted metabolic pathways, while host health remained largely stable, suggesting microbiome plasticity and ...

Influence of Tank Coloration in Modulating Physiological Growth, Survival and Skin Pigmentation Expression in Nursery‐Reared Channa striata

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Tank colour is a crucial environmental factor that influences growth performance; however, its effect on Channa striata fry under laboratory environments is not widely recognized. This study investigated the influence of tank coloration on growth, survival, cannibalism, and pigmentation of C. striata larvae under nursery rearing conditions.

Deformation‐Aware Keypoint Detection and Stereo Morphometry for Free‐Swimming Fish on Edge Devices

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This study presents a deformation‐aware keypoint detection and stereo morphometry framework for real‐time body‐size measurement of free‐swimming fish on edge devices. By combining StereoFish‐D4, deformation‐aware landmark detection, calibrated stereo reconstruction, and spline‐based body‐length (BL) estimation, the proposed method achieves accurate ...
